Earlier today, the commit queue landed r103091, which broke layout tests because of a duplicate expectation: http://build.chromium.org/p/chromium.webkit/builders/Webkit%20Win/builds/10009/steps/webkit_tests/logs/stdio
It would be excellent if the commit queue could lint-test-files prior to landing.
I thought the style-queue already did such linting? Maybe the style-queue was down when that landed?
I think style queue does the linting, but the cq+ was given about a week after the patch was r+'ed. The duplicate crept in during that time.
I'm happy to review a patch that add this feature, but I'm unlikely to write one myself.
I've also been thinking that we should and a separate step on the bots to check the expectations (and then make them non-fatal when running the layout_tests); see bug 74762 for that.
